I have some snowboard-wear (gore-tex) that I want to clean. Anyone know of any places where I can do chemical cleaning of these - in Zurich/Zug area ?
Be careful. A hand-wash, even a machine wash is likely to be better than dry-cleaning.
At a ski (or outdoors) shop you should find products to wash waterproofs, and to re-waterproof. We did it in the washing machine.
This is what we used. https://www.nikwax.com/en-gb/product…ing/tech-wash/
If the wrinkling is only near the stitching then perhaps, somehow, the cotton shrunk but this normally only happens at high temperatures.
The other thing that can cause wrinkling is if the laminate outer, or inner layers shrinks relative to the Goretex layer.
You can dry clean Goretex but as with water washing, you'll need to reproof afterwards and the best way is with wash-in products (but then you get it wet which is what you are trying to prevent.
My Goretex products get wet over time anyway, with or without washing - from rain on the outside and sweat on the inside.
Careful handwashing isn’t going to do any more harm than wearing them in conditions for which they were designed.
To the OP: If your clothing has lost that water repellency and you want to wash them yourself - I use Nikwax Tech. Wash for washing and TX.Direct Wash-In to restore the water repellency.
I’d ask the clothing manufacturer about the existing wrinkling.
